Alkali-resistant iav fiber mesh daim ntaub yog cov khoom siv rau kev txhawb nqa cov cement (pob zeb). Nws qhov tseem ceeb tshaj plaws yog tias 16.5 feem pua zirconia tau nkag mus rau hauv cov iav tivthaiv, uas tuaj yeem tiv thaiv kev yaig ntawm cov tshuaj alkaline hauv cov cement, yog li txhim kho qhov zoo ntawm cov cement mortar. Impact resistance, tensile resistance, bending resistance, crack resistance, thiab impermeability tau lees paub thiab nyiam los ntawm cov kws tshaj lij hauv kev tsim kho thiab cov khoom siv science.
Tsav los ntawm lub teb chaws kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig txoj cai, sab nrauv phab ntsa rwb thaiv tsev tshuab tau tsim sai heev. Lub "polystyrene board polymer mortar sab nraud thermal rwb thaiv tsev system" thiab "cov roj hmab hmoov polystyrene particle thermal rwb thaiv tsev slurry system" tau pom zoo los ntawm Ministry of Construction tau siv dav hauv ntau lub tsev pej xeem thiab thaj chaw nyob thoob plaws lub tebchaws. Ib yam uas lawv muaj nyob rau hauv ib qho yog tias txheej txheej saum npoo yog ua los ntawm cov cement thiab cov khoom siv ntxiv raws li cov khoom siv cementitious, thiab alkali-resistant iav fiber mesh yog siv los ua cov khoom siv ntxiv los ua ib qho kev tiv thaiv sab nraum txheej rwb thaiv tsev. Qhov no tsis tsuas yog daws cov tiam ntawm micro-cracks nyob rau hauv cov txheej txheem solidification ntawm cement polymer slurry, tab sis kuj xyuas kom meej tias cov plastering nto txheej tsis muaj kab noj hniav, tsis muaj kab nrib pleb, tsis poob tawm, thiab zam kev puas tsuaj rau lub rwb thaiv tsev txheej los ntawm huab cua hnyav.
Lub hauv paus ntawm tag nrho cov phab ntsa sab nraud thermal rwb thaiv tsev yog thermal rwb thaiv tsev, thiab qhov tseem ceeb nyob ntawm qhov kev txhawb zog ntawm cov khoom siv. Alkali-resistant iav fiber mesh daim ntaub yog unmatched los ntawm lwm yam ntaub ntawv reinforcing. Vim:
1. Cov nyhuv ntawm alkali-resistant iav fiber mesh daim ntaub yog qhov pom tseeb, uas tuaj yeem ua rau lub zog tensile ntawm cov cement polymer mortar ntau dua 3 zaug, lub zog khoov ntau dua 4 zaug, thiab qhov cuam tshuam lub zog ntau dua 20 npaug. . Lub elastic modulus ntawm alkali-resistant iav fiber mesh daim ntaub yog 80 MPa, thiab elongation ntawm so yog tsawg dua 2.4 feem pua, uas yog sib npaug rau expansion thiab contraction coefficient ntawm cement polymer mortar. 90-degree deformation yuav tsum tau zam kom tsis txhob muaj qhov tsis zoo ntawm kev siv cov nets los tsim cov kab noj hniav.
2. Cov alkali tsis kam ntawm alkali-resistant iav fiber mesh daim ntaub yog zoo dua li qhov nruab nrab, tsis muaj alkali, thiab alkali-resistant coated mesh daim ntaub. Qhov tseem ceeb sib txawv ntawm lawv yog tias muaj zirconium-nplua nuj interface nyob rau saum npoo ntawm alkali-resistant iav fiber ntau, uas tuaj yeem txo cov concentration ntawm hydroxide ions hauv cov tshuaj alkali thiab inhibit nws qhov nrawm nrawm ntawm cov iav fiber ntau, li no txhim kho cov alkali tsis kam ntawm iav. Kev tshawb fawb los ntawm National Institute of Building Materials tau ua pov thawj tias lub zog ib nrab-lub neej ntawm alkali-resistant iav fiber mesh tuaj yeem ncav cuag 100 xyoo. Qhov nruab nrab thiab alkali-dawb iav fiber ntau mesh daim ntaub yog npog nrog ib txheej ntawm tshuaj tiv thaiv corrosion gel tsho tiv no (feem ntau PVC resin) rau saum npoo ntawm cov ntaub nrog kev pab los ntawm lub cev muaj zog. Thaum cov txheej txheem ntawm "lub tsho tiv no" puas los ntawm ib qho kev quab yuam sab nraud thaum tuav thiab kev tsim kho ntawm qhov chaw, nws cov alkali tsis kam deev yuav tsis lav. Cov tuam txhab tshaj lij nyob sab Europe thiab Asmeskas cog lus tsuas yog 20 txog 30 xyoo ntawm kev nyab xeeb lub sijhawm rau lub zog ntawm cov ntaub mesh siv. Qhov laj thawj tseem ceeb yog tias tsis muaj kev tshawb fawb hauv paus rau alkali tsis kam ntawm nruab nrab thiab alkali-dawb coated mesh daim ntaub.
3. Muaj qhov sib txawv loj ntawm qhov tuav ntawm alkali-resistant zog ntawm alkali-resistant iav fiber mesh daim ntaub thiab nruab nrab-, alkali-dawb, thiab alkali-resistant coated mesh daim ntaub. Raws li kev ntsuam xyuas ntawm alkali tsis kam lub zog tuav tus nqi los ntawm National Building Materials Research Institute Testing Center thiab Beijing Building Materials Inspection Station, alkali tiv thaiv lub zog tuav tus nqi ntawm lub qub yog ntau dua 90 feem pua, thiab tom kawg yog tsawg dua 70. feem pua. Nws tau raug pov thawj tias ntev npaum li cov ntsiab lus ntawm zirconia ntau dua 14.5 feem pua, Nws tuaj yeem ua kom ntseeg tau tias cov alkali tiv thaiv lub zog tuav tau ntau dua 90 feem pua. Txawm li cas los xij, nws tsuas yog siv sijhawm 1 mus rau 2 hnub txhawm rau txheeb xyuas cov ntsiab lus ntawm zirconia los ntawm cov txheej txheem tshuaj, uas yooj yim thiab nrawm, ua rau nws yooj yim heev rau cov koom haum kuaj thiab cov tuam txhab tsim kho kom paub qhov zoo tshaj plaws.
4. Lub lag luam alkali-resistant iav fiber mesh tau raug cuam tshuam loj heev. Txij li tus nqi ntawm cov ntaub mesh suav txog li ntawm 4 feem pua ntawm cov nqi tsim hluav taws xob ntawm sab nrauv phab ntsa rwb thaiv tsev, tus nqi ntawm alkali-resistant mesh daim ntaub tsuas yog 0.4 feem pua siab tshaj qhov nruab nrab thiab alkali-dawb mesh. daim ntaub, tab sis nws tsis lav qhov kev nyab xeeb ntawm tag nrho cov system.
Nrog rau txoj kev loj hlob ntawm kuv lub teb chaws lub zog-txuag thiab thermal rwb thaiv tsev technology thiab kev lees paub ntawm kev ua tau zoo ntawm alkali-resistant iav fiber ntau los ntawm cov neeg nyob rau hauv lub tsev cov ntaub ntawv thiab kev tsim kho kev lag luam, nws yuav twv yuav raug hu txhim kho txoj kev loj hlob ntawm sab nrauv phab ntsa thermal rwb thaiv tsev system nyob rau hauv ib tug noj qab nyob zoo, kev coj noj coj ua, thiab kev nyab xeeb.
